Method of domain decomposition in vibrations of mixed edge anisotropic plates (Q1328738)

This paper presents a study on the flexual vibration of anisotropic plates with mixed discontinuous periphery boundaries. A newly developed domain decomposition method is used to derive the governing eigenvalue equation. In the solution process, the complex plate domain is decomposed into appropriate subdomains. The displacement functions of each subdomain are represented by sets of orthogonally generated polynomials that satisfy the essential geometric boundary conditions. A comprehensive range of frequency parameters and deflection mode shapes of anisotropic plates with different mixed edge configurations are obtained. The effects of fiber orientation and the partial mixed ratio on the vibrational response of these plates have been investgated in detail.
